2 Claims. I

This invention relates to trigger locks for guns such as, shot guns orrifles. However, if found desirable, the device might also be adaptedfor use upon small arms such as pistols and revolvers.

The principal object of the invention is to provide a simple andefiicient attachment for removably mounting inside the trigger guard ofa gun, with stop elements of the lock disposed back of the triggers andin contact therewith, for preventing the triggers from being pulledbackward as is necessary in the firing of the gun, thus preventing achild, or other person through carelessness, from accidentally firingthe gun.

Another object of the invention is to provide a slotted lug of metal orother suitable material, the same being adapted to slide upon thetrigger guard of the gun immediately back of the trigger of a singletrigger gun, or between the triggers of a two trigger gun, with meansfor releasably securing the lug in place upon the trigger guard, and inthe case of a two trigger gun with means extended rearwardly and back ofthe rear trigger for preventing same moving rearwardly for firing theassociated barrel of the gun.

With the stated objects in view, together with such further andadditional objects and advantages as may appear from the specification,attention is directed to the accompanying drawing as embodying certainpreferred forms of the invention, and wherein:

Figure 1 is a side elevation of the trigger section of a two-triggergun, showing the trigger and triggers therein, and showing mounted inplace within the guard and between the triggers thereof, the form of theinvention as designed for locking both triggers to non-firing position.

Figure 2 is an enlarged perspective and detail view of the lock assemblyas shown in Figure 1, the triggers and guard being broken ofi.

Figure 3 is a plan view on the scale of Figure 2, showing the triggerlock as removed from the gun, and showing the fixed trigger stop or lockfor locking the rear trigger of a two-trigger gun, and in full anddotted lines the slidable mounting of the upper trigger stop for lockingthe forward trigger of the gun.

Figure 4 is a rear end view of the device as shown in Figure 3.

Figure 5 is a cross section on the line 5-5 of Figure 3, and showing indotted lines the lower rib of the trigger guard upon which the device ismounted.

The invention as referred to comprises a lug 5 of metal or othersuitable material and preferably rectangular and oblong in form asshown.

This lug is slotted out through its ends and one side, and so that saidslot has an upper and a lower side only, in parallel with the upper andlower sides of the lug, as shown at 5a, the said slot being dimensionedto nicely receive and engage the lower rib 6a of the trigger guard 6 ofthe gun 1. The lug is bored and tapped centrally through its lower lip5b, as shown at '50 for threadedly receiving and passing a set screw 8,whereby the lug may be removably mounted in place upon the said rib 6a,of the trigger guard between the triggers 9, I0, of the two-trigger gunI, as shown. For use upon such two-trigger gun the lug 5 is formed witha rearwardly extended rear trigger hook or stop 5d which passesimmediately back of the rear trigger Ill and prevents the rearward orfiring movement of that trigger. The upper side of the lug 5 ischambered or routed out longitudinally as shown, to form a slide-way 5eof uniform depth and parallel margins, the same being thus adapted forslidably receiving the lock-slide II which is longitudinally slotted asat Ha. for freely passing a headed set-screw I2 which is seated in acomplementally tapped bore 5 formed centrally and perpendicularly downinto the upper side of the lug 5. Thus this lock-slide ll may be pushedforwardly against the forward trigger 9 and locked in position byturning down the set screw I2, for preventing the rearward or firingmovement of the trigger 9.

The foregoing description completes the disclosure of the invention asthe same is formed and assembled for use upon a two-trigger gun, such ashere represented, and it is thought that the explanation as given, theoperation and use of the device will be readily understood.

While I have herein shown and described a particular embodiment of theinvention and specific structural features thereof, this constructionmay be changed or varied as desired, within the scope of the appendedclaims.

I claim:

1. In a device of the kind described for mounting upon the lower rib ofthe trigger guard of a two-trigger gun, means for locking the triggersagainst rearward movement for firing the gun, the said means comprisingan oblong rectangular lug slotted out through one side and both ends, sothat said slot has an upper and a lower side only, extended in parallelwith the upper and lower sides of the lug, and whereby it may be mountedon the guard rib inwardly of the guard and between the two triggers, aset screw passed upwardly through the lower lip of the lug as formed bythe slot and adapted to bear upon the guard rib as means for securingthe lug in place, a stop hook extended rearwardly from the lug andadapted to pass rearwardly of the rear trigger, a longitudinally slottedlock-slide slidably mounted upon the upper side of the lug, and a setscrew passed through the slot of the lock-slide down into the lug,whereby the slide may be pushed forwardly against the rear side of theforward trigger and locked in position by means of the set screw.

2. A trigger lock for a gun having a firing trigger oscillatablyextended at its under side for firing the gun on its rearward movement,and having a trigger-guard-rib extended over the free end of thetrigger, the said lock comprising a rectangular lug slotted out throughits ends and one side, and so that said slot has an upper and a. lowerside only, in parallel with the upper and lower sides of the lug, andwhereby it may be re movably mounted upon the said trigger-guardribeither forwardly or rearwardly of the trigger, by passing the; guard-ribinto the said slot. releasable means for securing the slotted lug inposition upon the trigger-guard-rib, and means extended rearwardly fromthe lug, when same is mounted forwardly of the trigger, for lockinglyengaging the trigger to prevent its rearward movement for firing thegun.
